Abstract: Systems and methods for minimizing or eliminating steps in immunosorbent assays for single and multiple analytes by eliminating the need to attach target molecules to test well and the need to remove unbound antibodies through rinsing. Immunosorbent assay (ISA) is utilized for a single analyte and includes the step of mixing the immunologic molecules with the sample and detection. Immunosorbent assay for multiple analytes for testing a plurality of analytes in a single well is disclosed using a modified ISA test wherein different tags are attached to different antibody pairs. Alternate embodiments use multiple types of scavenger antigens with corresponding elimination of the need for scavenger antibodies. Various types of test wells are disclosed for rapid and simultaneous testing of fluids for a plurality of components and methodology for continuous immunosorbent assay. Method for immunosorbent assay of an analyte object having a plurality of distinct target antigens is also disclosed.

Abstract: The present invention discloses systems and methods for minimizing or eliminating steps in immunosorbent assays for single and multiple analytes by eliminating both the need to attach target molecules to the test well and the need to remove unbound antibodies through rinsing. The immunosorbent assay (ISA) is utilized for a single analyte or target and includes the step of mixing the immunologic molecules with the sample and detection. The present invention further discloses an immunosorbent assay for multiple analytes (ISAMA) for testing a plurality of analytes or targets in a single well using a modified ISA test wherein different tags are attached to different antibody pairs. Alternate embodiments use multiple types of scavenger antigens with corresponding elimination of the need for scavenger antibodies. The present invention discloses various types of test wells for the rapid and simultaneous testing of fluids for a plurality of components and a methodology for a continuous immunosorbent assay.

Abstract: The present invention discloses an apparatus and method for minimizing or eliminating steps in immunosorbent assays by eliminating both the need to attach target molecules to the test well and the need to remove unbound antibodies through rinsing. The single-step immunosorbent assay (SISA) includes the step of mixing the immunologic molecules with the sample and detection. SISA is utilized for a single analyte or target. The present invention further discloses a single-step immunosorbent assay for multiple analytes (SISAMA) for testing a plurality of analytes or targets in a single well using a modified SISA test wherein different fluorescent tags are attached to different antibody pairs. The present invention further includes various types of cassettes having test wells for the rapid and simultaneous testing of fluids for a plurality of components. Embodiments of this invention uniquely utilize colorimetric reagent reactions for ease of testing.
